[PATCH] HTTP: add support for trailers in HTTP responses

[Valentin V. Bartenev]

My two cents.

If somebody wants nginx to support trailers then why not,
as long as this feature is optional.

I think nginx mustn't be used as "political lever" if one
of the developers dislike the concept of some feature,
don't want to see use-cases and thinks that the only
purpose is to push some technology by well-known company.

It's too naive to think that we can change something by
denying some feature.  The only result of such stubbornness
is that our users will have to choice other alternatives to
nginx or have to invent their own solutions.

I strongly suggest moving the debate to more constructive
ground, and instead of keep refusing think about how we can
introduce trailers support in the most clever way.
